Local volatilities predict \ the change of implied volatility with stock price, and that local volatility varies twice as fast with spot as implied volatility varies with strike. Studied its dynamics over different market regimes. The Hull‐White model has been chosen as it is both simple and rich enough to illustrate the power of component‐based programming in Python. It can readily deal with complex financial products, for instance options involving early exercise features, and with advanced asset pricing processes, such as stochastic local volatility models. We tackle the calibration of the Stochastic Local-Volatility (SLV) model. dent interest one of its main applications is the calibration of the local volatil-ity model (Derman and Kani 1994, Dupire 1994, Rubinstein 1994), where the volatility of the spot is a deterministic function of the spot and time. max_sharpe() to weights = ef. For a given date, time(t) and the underlying stock price(St), a local volatility is derived from the equation that options price calculated with the local volatility equals to the market options price.
